ABSTRACT
Objective To discuss the risk factors of progressive hemorrhagic injury(PHI)in patients with craniocerebral injury.Methods Clinical data of 149 patients with closed craniocerebral injury were retrospectively analyzed,and the patients were divided into PHI group (42 cases)and non -PHI group (107 cases)according to PHI appeared or not.The patients were immediately given CT scan after admitted,the first CT review was given in the non -PHI group within routine 4 -8h after first CT scan,and due to deterioration of clinical symptoms,the PHI group was given CT review in advance.The intracranial hematoma volume changes between first CT and first CT review in the two groups were observed,then clinical symptoms,signs,biochemical indicators and CT performance in the two groups were compared,and analyzed risk factors of PHI.Results The intracranial hematoma volume showed in CT scan,first CT review and increment volume of the PHI group were significantly higher than the non -PHI group [(14.59 ±4.60)mL vs.(7.28 ±2.94)mL,(25.92 ±8.84)mL vs.(8.35 ±3.41)mL,(10.20 ±3.45)mL vs. (2.10 ±0.65)mL],the differences were significant (t =6.796,11.894,9.367,all P 10mL were major risk factors of PHI (P 50 years old,mydriasis,conscious disturbance,intracranial hematoma volume >10mL in first CT scan.
